SKI BINDING Filed June 12, 1933 Patented Oct. 2, 1934 UNITED STATES PATENT OFFICE Application June 12, 1933, Serial No. 675,405 In Norway June 22, 1932 3 Claims.

My invention relates to ski bindings of the kind which may be fastened to the foot simply by stepping into them and without having to reach down for fastening them, resilient means being 5 provided which slip into corresponding grooves provided in the heels or in mountings fastened to the heels.

According to my invention, I arrange these resilient means in the shape of resilient tongues bent up from a resilient heel plate, the arrangement being such as to obtain a double spring action, the heels when trod down not only forcing back the resilient tongues, but also bending simultaneously the heel plate proper downwards towards the ski. This double spring action facilitates the fastening of the binding as well as its release.

In the accompanying drawing is illustrated a preferred executional form of my improved ski binding.

Figs. 1 and 2 are, respectively, a perspective view and a side view of my ski binding.

Figs. 3, 4 and 5 illustrate details of the adjusting means, in top view, sectional view on line 1-1, Fig. 3, and bottom view, respectively.

In the drawing, 1 are the rigid toe lugs, to which the heel plate 5, 5 is connected by means of links 2 and arms 4, the connection between the latter and the plate member 5 being established by aid of rivets or bolts 3, which are drawn so tight that the interconnection may normally be considered as rigid, but may also allow slight adjustments transversely to the ski.

The heel plate proper 5' is made of resilient material, such as steel or the like which is adjustably connected with the heel plate part 5, and it is provided with resilient bent-up tongues 6 and with a release tongue '7. In order to increase the double spring action mentioned above,

40 the heel plate 5 is provided with a narrow neck 5" in front of the tongues 6. As shown in Fig. 2, the rear part of the heel plate 5 is normally positioned slightly above the upper face of the ski in such manner that, on pressing down the heel simultaneously with the pressing back of the tongues 6, the back portion of the plate 5' is bent downwards. The plate 5' is bent around the plateshaped member 5 and is adjustable along the same. The plate 5 is provided with a longitudinal slot 8 having teeth 9 along both edges. In an opening in the member 5 is placed a locking member 10 (Figs. 3 and 4) provided with corresponding teeth which are normally in engagement with the teeth 9, and this member 10 is kept locked in this position locking the members 5 and 5 together by means of a part 12, through the intermediary of a spring 11. The ends of this spring engage corresponding depressions 11 in the member 5 locking the part 12 in the transverse position shown in Fig. 1, and 50 interlocking also the members 5' and 5 through the agency of the member 10. When, however, the parts 11 and 12 are turned about their central pin 12 to the longitudinal position shown in Figs.

3, 4 and 5, the part 12 together with the member 10 firmly connected to it, may, by pressure from above, be depressed so as to come out of engagement with the teeth 9 and be adjusted to a new position in relation to the said teeth. As soon as the pressure on the part 12 (or the pin 12) leaves off, the spring 11 draws it again up with the part 10 in engagement with the teeth 9.

I claim:

1. In ski bindings the combination of a resilient heel plate having its back part raised above the ski, resilient tongues bent up from said heel plate, a plate enclosed by said heel plate, adjusting means interconnecting said plates and means interconnecting said enclosed plate and the rigid toe lugs of the ski, comprising arms fas- 0 tened to said enclosed plate and links hinging said arms to said toe lugs.

2. In bindings the combination of a resilient heel plate having its back part raised above the ski, resilient tongues bent up from said heel plate, a plate enclosed by the front part of said heel plate, adjusting means interconnecting said plates, comprising a slot in said enclosed plate, tooth racks along the sides of said slot, a looking member having teeth normally in engagement with said tooth racks, a spring keeping said locking member in engagement with said racks, and means connecting said enclosed plate to the rigid toe lugs of the ski.

3. In ski bindings, the combination of a resilient heelplate having its back part raised above the ski, resilient tongues bent up from said heel plate, and adapted to engage corresponding grooves in the heels of the skiers boots, a plate longitudinally adjustable with respect to said heel plate provided with rigid toe lugs, adjusting means interconnecting said plates, and means connecting said adjustable plate to the rigid toe lugs of the ski, comprising arms fastened to said plate and links hinging said arms to said toe lugs. 1G5
